We look at the division of 21351470 by 444 
Let's see how many times 444 fits into 21351470.

Step 1:
444 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 444

Going ahead to step 2:
21 divided by 444 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 444

Moving on to step 3:
444 goes into 213 0 times with a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Grab the next digit (5) from the dividend, add it to 213, then carry on: 2135 / 444

Step 4:
When dividing 2135 by 444, we get 4 with a remainder of 359.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1776 from 2135 leaves us with 359.
Bring next digit (1) of the dividend behind the 359 and repeat the process: 3591 / 444

Let's proceed to step 5:
444 goes into 3591 8 times with a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 48.0
If we subtract 3552 from 3591, we get 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 444

Moving on to step 6:
444 can be fit into 394 0 times, resulting in a remainder of 394.
Record the quotient 0 as the next digit in the result. 
Result so far: 480.0
Subtract 0 from 394 to get 394.
Append the next digit (7) from the dividend to 394 and continue with: 3947 / 444

On to step 7:
444 goes into 3947 8 times with a remainder of 395.
Record the quotient 8 as the next digit in the result. 
Result so far: 4808.0
If we take 3552 away from 3947, we end up with 395.
Include the next digit (0) from the dividend after 395, then repeat: 3950 / 444

Going ahead to step 8:
The number 444 fits into 3950 8 times, leaving a remainder of 398.
Use 8 as the next digit of our solution. 
Result so far: 48088.0
If we subtract 3552 from 3950, we get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Moving on to step 9:
444 can be fit into 3980 8 times, resulting in a remainder of 428.
The number 8 becomes the next digit in our result. 
Result so far: 48088.8
Deduct 3552 from 3980 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 10:
When dividing 4280 by 444, we get 9 with a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 48088.89
Subtract 3996 from 4280 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 11:
444 goes into 2840 6 times with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 48088.896
Deduct 2664 from 2840 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

On to step 12:
444 goes into 1760 3 times with a remainder of 428.
Put 3 as the next digit of the answer. 
Result so far: 48088.8963
If we take 1332 away from 1760, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

On to step 13:
If we divide 4280 by 444, we get 9 and a remainder of 284.
The next digit of our result is 9. 
Result so far: 48088.89639
Deduct 3996 from 4280 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 14:
If we divide 2840 by 444, we get 6 and a remainder of 176.
The next digit of our result is 6. 
Result so far: 48088.896396
If we subtract 2664 from 2840, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Moving on to step 15:
The number 444 fits into 1760 3 times, leaving a remainder of 428.
Record the quotient 3 as the next digit in the result. 
Result so far: 48088.8963963
The remainder is 428 after subtracting 1332 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 16:
When dividing 4280 by 444, we get 9 with a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 48088.89639639
If we take 3996 away from 4280, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 48088.89639639 with a remaining 2.84e-07.
